When reassembling the fan housing, make
sure the fan wheel is balanced and centered in
the fan housing and not rubbing on either side.
Clean up debris on the fan wheel before start-
up.
Change Motor
The Fan Coil will not operate properly without
a functionally normal motor. If the motor fails,
order a replacement from the Trane
Company. The motor should be replaced by
completing the following steps:
1. Turn off the electrical power source and
then disconnect the motor wires. Allow
the rotating fan wheel to stop.
2. Disconnect the grounding wire on motor
shell.
3. For the motor with two fans, the fans must
be removed first before changing the motor.
Follow the "Change Fan Housing/Fan
Wheel" steps to remove one fan out of the
unit and motor shaft.
4. Loosen the bolt, on the other fan wheel,
from the motor shaft.
5. Loosen the screw and nut on two clamps
which hold the motor and motor seat
together, as shown on Figure 8-5 & 6.
6. Open the clamps and then remove the
clamps out of motor seats, as shown on
Figure 8-7. Hold the motor with one hand,
when removing the second clamp, to
prevent the motor from dropping off.
7. Follow the opposite procedures to reinstall
the new motor.
After replacing the motor, make sure the fan
wheel is balanced and centered in the fan
housing and not rubbing on either side.
Motor oil
Bearings are sealed for life and do not
require periodic lubrication.
Maintenance
Coil Reversing
1. Unscrew the bolt fixing the drain pan and
units.
2. Remove the drain pan.
3. Unscrew the bolt fixing the bottom plate
and units.
4. Remove the bottom plate.
5. Unscrew the bolt fixing the coil and units.
6. Rotate the coil for 180
°
.
7. Reinstall the coil on the opposite
procedure.
Notes: The coil reversing should be completed
before hoisting.
Coil Cleaning
Clogged or dirty coil will reduce the cooling
capacity. Followings are the cleaning steps:
1. Disconnect the power and motor wire and
stop the fan.
2. Remove the whole fan seat and clean from
the air inlet.
3. Clean the coil fin using rigid nylon brush.
4. Clean it with dust collector.
5. Clean with high-pressure nozzle if there is
any compressed air.
6. Straighten the bended fin.
7. Connect the power again.
No need clean the coil if the filter is used and
periodically cleaned.
Drain Pan
The drain pan should be cleaned to allow
condensate flow. If it is clogged, steps
should be taken to clear the debris so that
condensate will flow out easily.
